I think their point is that Democrats aren't progressives. They're Neo-Liberals, aka, conservatives.

I personally have to hold my nose and vote for Democrats when the party puts forth the most milquetoast conservatives that they can possibly find. Hell they had to run an 80 year old candidate just to find someone that agrees with the DNC corporate policies.

This isn't to say both parties are the same. They aren't. The Republicans are absolutely fascists that want to destroy democracy because it doesn't work for them at all. The Democrats are only willing to work with democracy because it's working for them thus far.
